Tectibranchs of the Bermudas. 549 



Color nearly pure white. Length, in life, about 1 2™°^. Probably- 

 young. 



Bailey Bay Island, at low-water mark, among corallines. One 

 example. 



Lamellidoris (?) quadrimaculata, sp. nov. 

 Plate LXVI. FisaRE 3. 



Body much flattened, broadly elliptical in life, with wide, thin, 

 undulated mantle margins. Rhinophores conical, subacute, plicate, 

 white, without distinct sheaths. Eyes small, nearer together than 

 the rhinophores. Gills five, small, white, much branched. Back 

 covered with minute spiculose papillte, light orange-yellow with 

 a darker orange wide median patch, and specked with numerous 

 very small flake-white dots and with four larger, very distinct, 

 prominent, round white spots, arranged in a quadrangle on the 

 middle region of the back; numerous branching and reticulated thin 

 white lines run out radially toward the margins of the mantle, above 

 and below, and seem to be due to spicules imbedded in the tissues. 



Length about 12'"°^; breadth, 6 to 8™"". 



Castle Harbor, on dead corals, April 18. Two examples. 



Chromodoris (?) roseopicta, sp. nov. 

 Plate LXVI. Figure 1. 



Body broad-ovate, subtruncate in front, obtuse behind ; marginal 

 ridges elevated and undulated in life. Gills rather large and numer- 

 ous (about 16), elongated, simply pinnate. Rhinophores with a stout 

 sheath. Dorsal area, except in middle, covered with rather numer- 

 ous small conical papillae, which form a single row behind the gills 

 and near the front of head. 



Ground-color of dorsum and sides bluish gray, but thickly specked 

 with black and flake- white dots, these specks largest on the back ; 

 marginal ridge edged with bright carmine or rose-red, with a sub- 

 marginal line of white ; dorsal papillae, rhinophore-sheaths, and tips 

 of gills also carmine-red ; outer margin of foot carmine or orange 

 red.
